What breed is my Rooster

[TheOddOneOut]

yeah now that you point those things out I agree, it's definitely a stretch

He may be a RSL mix..but I’m not sure.

Maybe some creme legbar, or some ISA brown. Maybe some orpington, but very little

Where do you get cream legbar from?

I would bet that your big boy is a white leghorn x Rhode island red mix ( or at least something very close to that)
most leghorn RIR crosses come out with more red but it all depends on if the bird leans more towards the mom's coloring,or the dads
here is a leghorn rir mix photo I found online.
Hope this helps!

For one, he has a pea comb.
